Patent JP-H0678538-A (JP)
Title: Ac switching circuit apparatus
Inventor: KUMAGAI NAOKI
IPC: H02M5/257
Filed: 1992-08-27
Abstract: PURPOSE:To prevent a break-through of a thyristor, by providing a self-arc- extinguishing type semiconductor element connected in parallel with the thyristor, and by making the semiconductor element turn on in the lower dV/dt value than the dV/dt-withstanding quantity of the thyristor. CONSTITUTION:In the state wherein the voltage-time-varying rate dV/dt of the voltage applied to a MOS FET (SE4) is lower than the dV/dt-withstanding quantity of a thyristor, a voltage drop (Vr) of a resistor 5, which is caused by a displacement current (Ic) flowing through the resistor 5, becomes the voltage value exceeding the ignition voltage (Vth) of the FET SE4, and a drain 4a of the FET SE4 is connected with its source 4b in a conducting way. Therefore, the bypass of a thyristor 2 is generated between an anode 2b and cathode 2a of the thyristor 2 by the FET SE4, and the potential difference between the anode 2b and cathode 2a is reduced to a small value violently. Thereby, the varying ratio of a reverse recovery current (Irr) of a thyristor 1 is decreased, and the dV/dt value applied to the thyristor 2 between its anode 2b and its cathode 2a is reduced, and in its turn, the break-through of the thyristor 2 is prevented.

Title: Device for limiting drive slip
Inventor: MIHIYAERU FURIIDOFU
IPC: B60T8/42
Filed: 1988-09-13
Abstract: PURPOSE: To provide space-saving constitution by forming a driver as an electromagnetic driver. CONSTITUTION: A control device 12 recognizes the presence of a driving slip and the magnitude of its rise, from the time intervals of signals from wheel speed sensors 8, 9 for driveable wheels and wheel speed sensors 25, 26 for wheels which are not driven. For example, when a driving slip exceeding an inconvenient slip value occurs at a driving wheel fitted with a wheel brake 6, the control device 12 controls a valve 10 to a locking position and excites an electromagnetic driver 5 by the method of pushing its pressure rod 21 toward the piston 14 of a brake pressure generator 3. Therefore the piston 14, within a cylinder 13, forms a pressure working on the wheel brake 6 through a connecting opening 18. As the driving slip decreases, the drive 5 is returned to a basic position and the valve 10 is opened. The wheel brake 7 is driven in the same way.

Title: Laminate body
Inventor: HARA TADANAO
IPC: B29C43/18
Filed: 1992-08-27
Abstract: PURPOSE:To provide a laminate body free from sink mark caused by the volmetric shrinkage of its base resin material and having a good appearance by a method wherein the base resin layer is provided with the projections formed integrally therewith and a hollow part is formed in the interior of the resin layer near an intersecting point of the base resin layer and the projection. CONSTITUTION:A hollow part 4 is provided in the interior of a base resin near an intersecting point of the base resin layer and a projection 3. This hollow part is formed by a method wherein the base resin material is previously mixed with a chemical foaming agent and the foaming agent is allowed to expand only near the intersecting point of the base resin layer and the projection upon molding or wherein a fluid is injected into the resin layer near the aforesaid intersecting point upon molding. The former method is effective when the base resin layer is relatively thin. When the resin layer is thick, however, it is possible that the resin layer may be wholly expanded to such an extent that the desired laminate product can not be obtained.

Title: Herbicidal formulation
Inventor: SATO MITSUNORI
IPC: A01N25/34
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a herbicidal formulation capable of persisting a herbicidal- effect over a long period. SOLUTION: This heribicidal formulation comprises the cured product of a molding material containing a thermosetting resin and a herbicide. The herbicide in the herbicidal formulation is dispersed in the thermosetting resin matrix, and is gradually eluted over a long period to maintain the herbicidal effect. Even when a large amount of water due to raining or the like acts on the herbicidal formulation, the herbicide is easily not eluted in the water, and the herbicidal formulation is not blown off due to the weight of the thermosetting resin. Thereby, the herbicide is left in soil over a long period to maintain the herbicidal effect.

Abstract: PURPOSE:To record information to each of plural photomagnetic recording layers by irradiating a laser beam to an photomagnetic recording medium com prising lamination of plural photomagnetic recording layers having different Curie temperatures while the output is being changed. CONSTITUTION:When an objective lens 70 is positioned by a driving coil 71 at a position apart from an photomagnetic disc 10, a laser ray irradiated from a laser light source 66 is collected onto the magnetic recording layers 20 to heat the photomagnetic material constituting the layers 20 to the Curie tempera ture or over thereby erasing the vertical magnetization stored therein. In this case, when a magnetic field is formed vertically by an electromagnet 74, a part corresponding to a beam spot heated by the laser ray reaches a tempera ture being the Curie temperature or below and then is magnetized vertically in a direction of the magnetic field formed by an electromagnet74. Thus, desired information is written in a desired location of the 2nd magnetic recording layer 20.

Title: Ion implantation device
Inventor: KIKUCHI SHUJI
IPC: H01L21/265
Filed: 1989-09-04
Abstract: PURPOSE:To prevent any charge-up at the time of ion implantation by radiating an electron to an ion beam implanted into the implanted body. CONSTITUTION:In an ion implantation device for implanting an ion beam into an implanted body, an electron is radiated to the ion beam implanted into the body. Namely, an ion to be implanted is neutralized by a low energy electron contained in plasma, to be implanted into the implanted body. A surface potential in the region of an insulative film of the implanted body cannot be increased up to such a level as to cause a dielectric breakdown. Any damage to the implanted body caused by a high energy electron can be reduced differently from the case of an electron shower. Therefore, any charge-up to the region of the insulative film on the implanted body can be prevented.
